To @Zlio/tom t may concern y Be it known that we, ALAN MAoKENzrE MCNEILL and VILLIAM JOHN Aeor'r, subjects ofthe King of Great Britain, residing at Auckland, in the Dominion of New Zealand, have invented newv and useful Improvements in Binder-'Cases for Document and like Files, of which the following is a specication. c

This invention relates to the binder cases usedin holding document, letter and like i'iles during the period of their filling, in order to protect such files and to provide a holder therefor in which they are held in positions such that the papersmay be readily placed in their proper ycompartments or withdrawn therefrom at' will.

The invention has been devised especially with the object of providing a binder ease adapted for use in conjunction with a file of book-like form, such as is described and covered by our Co-pending application for patent Serial No. 419,278. of even date herewith, and consisting of leaves bound together with expansible binding. Thisr case is designed to hold such a file within it and to keepit in a flat position and also to securely hold the papers within the iile in such a manner that they may be examined, whenever desired, either as 'to the major portions of their surfaces, or as to the toprightv hand corners, or the bottom right hand. corners, at will.

The invention consists in constructing the binder case of skeleton book cover form, having top and bottom covers of approved stiff material and a back hinge connecting them together, of the necessary width to provide for the two covers remaining parallel when the le within them is full to its great-` est capacity. The said bottom cover is provided with means whereby the file laid thereon may be held firmly in position.

Combined with this bottom cover is a band or strap of approved material and width that Aentends down from the upper to the lower edge of this cover and above the tile secured thereon. This band is provided with a buckle fastening, by means of which it may be drawn tight or loosened at will, and. it is connected to the cover, at both of its ends, by special means designed to allow for it being moved laterally across the width of the cover either in a line parallel with position therein.V

Fig. 2 is a lower edge view thereof, but

with the case closed.

Fig. l3 is a cross? sectional elevation of the' means fori attaching one `endl ofthe band o1" strap to the corresponding' edge of the case cover.

Figs'd and 5 are detail'views, respectively of portions ofthe'case bottom coverand vthe file, showing suitable meanswhereby the file may be secured to the said'cover;

The case is4 formed with ia stiff bottom cover A and top coverB connectedtogether by the stiff backC hinge connected to eachV of such covers and of thenecessaryvwidth to provide for thefiles capacity. It there'- fore, in effect, forms a skeleton booklsothatf.

a file of book form,"such`as'the alphabetical index form of file D "shownfinthedrawings may be laid with its' bottom cover uponv` the inside face ofthe bottom cover" A"k of the" binder case and when held therein may be opened and closed as a book. In placing documents in the file therefor, the case may be held with its back C downward on the lap and its bottom outward, when the different divisions ofthe lile may be easily seen and the leaves of the file parted at the required places to receive the documents.

Any approved means for attaching the file D to the cover A may be employed, providing they are of such a nature as to permit of the ile being readily removed, when full, and a fresh one placed in its position, as a refill. The means for this purpose shown in the drawings, consist in spring dome button fastenings secured upon the inner surface of the bottom cover A near its back edge, and upon the under surface of the bottorn cover of the file D, as shown in Figs.V

Secured along the inner surface of the boti position and with a file inV tom cover A at each of itsupper andlower edges, is a metallic slide` guide G that extends across practically the full width ofk such cover;l v .Thesaid guide isformed withrv overhanging upper and lower edges g. A slide vplate H is provided and is placed withinthe guide soas to extendbeneaththe edges gV in such a manner as to allow the plate to `'slide freely valong the guide, but to prevent it lifting` out. provided with lugs 7L projecting upward between the edges g, and in these lugs a bent wire loop J-ispivotedvrlChis loop is made of approved length and its outer end is made broad enough to allow oi the" broad band or strap K being 'passed around it and maintained in .ilat condition. vThe band or strap K thus provided is passedthrough and around both loops J so that it extends down across the fullheight of the cover, and its two ends are brought together andsecured by a buckle K or, like fastening. V The band tion, the hand being Y E. therefore extendsover the 50p of the le D and serves, when drawn tight, to hold the papers placed in such'file, securely in posiloosened andpushed right to the inner edge of the tile, lwhen papers are being tiled, by pushing the slide plates H in along the respective guide G.

0r, by positioning the band at about half way across thewidth 'of thetile, while keeping it taut, theouter edges of the ile may be turned up to allow of vany particular paper being located. Or, again, by moving one slide plate inward along itsguide and the otheroutward in its guide,lthe band may be arranged toV extend diagonally across the Vfile, asshown by the dotted lines in Fig. l, in

which position, the `freed outer corners of the file leaves and the papers therein may bey turned over, in'order to inspectl the dates or Athe signatures The slide plate is ot the papers, as the case may be.

To facilitate this positioning of the' band at Vthediagonal angles referred to,r` while A`maintaining its iiat condition,l each slide plate H is made with its edges that engages the guide sides', slightly rounded, as shown "in Figs. 1 and 3 so thatit may swivel in the vits bottom cover and` having slide guides fixed to extend laterally one across each of the upper and lower edges of the said vbottom cover, a slide plate mounted in each of such guides and adapted to move to and fro along it, a lloop pivoted to each of `such plates, and a band or strap passed through both of such loops and having means for securing its ends together.

2. A binder case for document and like i'iles constructed asdescribed in claim l, and

Vin which each slide plate is so formed that it may swivel within its guide.
